// Create a Bitmap object with the desired width and height
Bitmap bitmap = Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Bitmap.Config.ARGB_8888);

// Create a Canvas object with the Bitmap
Canvas bitmapCanvas = new Canvas(bitmap);

// Draw the content of the original Canvas onto the new Bitmap Canvas
canvas.drawBitmap(bitmap, 0, 0, null);

// Now you have a Bitmap object containing the content of the original Canvas
